A new firmware is out for the Sony Xperia V version 9.2.A.2.5. This update is available right now on Sony PC Companion software but no sign of it on the Update Center ( on the phone ).
As usual there were no release notes or what bug fixes the developers have done with the phone. But the phone feels snappier than before, memory usage is lower and camera with superior auto mode seems to have improved abit ( just my thought, I could be wrong ).
